Omplexity of human being and their moral actions

Human beings are complex. How is this evidenced in their moral actions? How does either (1) utilitarianism or (2) Kantian deontology reduce the complexity of human action? How does Aristotelian-Thomistic ethics evidence this complexity? Give an example of a complex human action and how it would be evaluated by either (1) or (2) and how it would be evaluated by Aristotelian-Thomistic ethics. You should discuss limits to morality, virtue and vice, good and evil actions, universal and prudential norms of human action, and the ways in which we become aware of natural law.
